A horizontal sealing device is provided which is provided with a transporting means for transporting a printed material to be packaged in the insertion space, and which is disposed on the downstream side of the former and melts and welds the tubular film formed by the former in a horizontal direction perpendicular to the transport direction. Provided, provided on the downstream side of the horizontal sealing device, provided with a vertical sealing device for welding both side edge overlapping portions of the tubular film, provided on the downstream side of the horizontal sealing device,
The technical means of providing a detection sensor for detecting the sealing position by the horizontal sealing device and providing a means for conveying and discharging the package sealed by the horizontal sealing device and the vertical sealing device are taken.

[0005]

Operation: The wrapping film is pulled by the drive roller,
While being supplied, it is inverted and molded into a thin hollow cylinder by a former. The film pulled out from this former in a tubular shape has the tip (horizontal side of the lower end) fused and welded by a horizontal sealing device, and then the article to be packaged is stored inside the tubular body,
Then, after the seal position is confirmed by the position sensor, the horizontal sealing device and the vertical sealing device perform horizontal sealing at the rear end and heat sealing at the overlapping portion in the vertical direction. The fusing takes place at the same time during the transverse sealing at the rear end, whereby the packaged articles are separated as individual packages. The separated packaged article is transported to the outside of the device.
